Another artist that I've seen at a few conventions, but never got the chance to get any art from, is Joe Pekar. Joe is an excellent artist who's sketches and pinups are all very vibrant. As you can see in the sketch of Harlette he did, Joe uses water colors, but this scan does not do his work justice. The color pops off the page in real life. Yet he still has this soft quality to his work. Great stuff and a super nice guy! Check out more of his work at http://www.joepekar.com/ and http://www.jfury.deviantart.com/ .
